The people who get reshaped need to kick themselves, kick the monstrosity, and the key difference, eat ONE pool. This gives each person enough time to stack 1-2 more amber strikes, thus allowing the stacks to chain between reshapes.
Assuming your dps is pretty good, realistically you will only need 3 people chaining stacks, with the fourth person stacking the boss further and staying in the vehicle for the remainder of the fight.
